I thought there was a way to persuade "svnadmin load" to keep the
revision numbers but on looking I cannot find anything. It seems to
renumber revs by default. However, I have a repository that I created
from a VSS conversion and used dumpfilter on and the revisions start at
282, so it must be possible somehow...

Working copies can be relocated (if you keep the same repo UUID) but I
believe that the renumbered revisions would still be a show stopper.
I'm confused now!
